Armed conflict is continuing in Sudan's South Kordofan and Blue Nile states, and approximately 200,000 refugees have fled to camps in South Sudan since 2011. These refugees face many health problems including malnutrition and respiratory tract infections, according to MSF's Silvia de Weerdt.

Last July, the world celebrated the birth of its newest nation as South Sudan officially separated from the north. It was hoped then that after decades of bloodshed, the people of of both nations would finally know peace.

In southern Sudan, most medical facilities were destroyed during more than two decades of civil war. Now, the dire lack of health clinics, the long distances involved in reaching them, often days of walking and the unattainable costs of care are all barriers to people seeking medical help.
